Flaws with The Rule of Two?

Didn't RoT fall apart after like the 4th generation anyway? Darth Millenial?

I mean, even Bane himself seriously considered disregarding the RoT when he began thinking that Zannah was too weak to usurp him... He, like many others, began looking for ways to expand his own life/power indefinitely and take multiple apprentices if need be.

So again, what is the explanation for the Banite Sith continually increasing in power with each generation despite treachery and unscrupulous methods being used to overthrow masters by weaker apprentices?

power=Dark Side knowledge. Not literal Force strength.

The ROT is inherently flawed. What if both parties die in a freak starship explosion or something?

Sith become extinct lol.

The Banite Sith definitely. But not the Sith in general.
